Michigan's child-welfare agency has filed detailed allegations of abuse against a Detroit man whose 12-year-old son was reported missing for days before he was found in the basement.

The state wants to terminate the parental rights of Charlie Bothuell IV. The agency also seeks to end the parental rights of Monique Dillard-Bothuell, the boy's stepmother and mother of two other children.

The state says Charlie Bothuell V was struck with a plastic pipe by his father and forced to do workouts.

The state says Charlie's stepmother ordered him to the basement on June 14. Charlie told caseworkers that he would sneak upstairs for food. Police found him after an 11-day search.

Bothuell's attorney declined comment. The stepmother's lawyer says there may have been legal "corporal punishment."
